Add a FreeBSD HID driver for the Sony PS5 DualSense gamepad (USB).
The hardware uses a vendor-specific HID descriptor which the generic
hgame driver cannot parse, so we replace it with a standard Game Pad
descriptor. Lightbar RGB LED and player indicator LEDs are exposed
through sysctl at dev.ps5dualsense.<unit>.
